The oceanic and atmospheric conditions the related climate impacts of 2015/16 ENSO cycle were analyzed, based on latest global observational data, especially that China. results show this strong El Niño event fully established in spring 2015 has been rapidly developing into one three strongest episodes recorded history. Meanwhile, it is also expected to be longest recorded, attributable stable maintenance abnormally warm equatorial Pacific Ocean since 2014. Owing event, along with warming...
Abstract The first Water Cherenkov detector of the LHAASO experiment (WCDA-1) has been operating since April 2019. data for year have analyzed to test its performance by observing Crab Nebula as a standard candle. WCDA-1 achieves sensitivity 65 mCU per year, with statistical threshold 5 . To accomplish this, 97.7% cosmic-ray background rejection rate around 1 TeV and 99.8% 6 an approximate photon acceptance 50% is achieved after applying algorithm separate gamma-induced showers. angular...
We present polarization pulse profiles for 56 millisecond pulsars (MSPs) monitored by the Chinese Pulsar Timing Array (CPTA) collaboration using Five-hundred-meter Aperture Spherical radio Telescope (FAST). The observations centered at 1.25 GHz with a raw bandwidth of 500 MHz. Due to high sensitivity (∼16 K/Jy) FAST telescope and our long integration time, signal-to-noise ratio show features hardly detected before. Among pulsars, PSRs J0406$+$3039, J1327$+$3423, J2022$+$2534 were not...
Designing the solid–electrolyte interphase (SEI) is critical for stable, fast-charging, low-temperature Li-ion batteries. Fostering a “fluorinated interphase,” SEI enriched with LiF, has become popular design strategy. Although LiF possesses low conductivity, many studies have reported favorable battery performance fluorinated SEIs. Such contradiction suggests that optimizing must extend beyond chemical composition to consider spatial distributions of different species. In this work, we...
Correlating the solvation structure and thermodynamic properties with transport serves as foundation for electrolyte design. While various physicochemical properties, such relative solvating power, energy, spectroscopies have been used to study ion solvation, fundamental investigations in of equilibrium across broad temperature ranges are not available. In this work, we combined temperature-resolved Infrared Raman systematically pinpoint dynamic evolution Li+-solvent Li+-anion local...
<title>Abstract</title> Objective To investigate the relationship between obesity and cognitive impairment among older adults using body mass index (BMI) weight-adjusted waist circumference (WWI). Methods Drawing on data from Chinese Longitudinal Healthy Longevity Survey database spanning 2011 to 2018, study employed Cox regression analysis restricted cubic spline method examine BMI, WWI, impairment.

We present first-principles calculations of the electronic structure oxygen vacancies in θ-Al2O3 and amorphous Al2O3 (am-Al2O3) using screened exchange (sX) hybrid functional. The sX functional can give correct band gap for both phases. defect energy levels depend strongly on charge state, with negative defects lying deep conduction band. Transition between different states were determined. 3-fold coordinated O vacancy dominates due to higher formation 4-fold vacancy. In am-Al2O3, only +1/0...
Abstract In this paper, radiosonde temperature time series (RTT) from 1958 to 2005 collected by the 116-station Chinese network are examined. Quality control and homogenization used obtain a reliable RTT. The results revealed significant discontinuities in Analysis suggested that 70% data availability is minimum requirement (MDR) for these RTTs. A new dataset built meeting MDR, which reduced number of potential stations 116 92. on reveals warming trends troposphere cooling stratosphere were...
Highland barley (Hordeum vulgare Linn. cv. nudum Hook. f.) is the principal cereal crop over Tibetan Plateau (TP). The response of highland barely to climate change in past decades, especially terms yields still remains uncertain. In this study, its responses were investigated using daily weather data and agriculture during 1961-2018. results showed that annual mean air temperature TP increased at 0.33 °C per decade 1961–2018, rate warming with altitude, reaching 0.41 altitudes 4500–4700 m....
Abstarct We used atmospheric air-temperature data from the Chinese radiosonde network to analyze changes in freezing-level heights (FLHs) during past 48 years and studied their impacts on cryosphere. examined time-series 92 selected stations. Generally, FLH exhibited a latitudinal zone, declining south. The trend 1958–2005 showed spatial inhomogeneity, most uniform distributions autumn, significant upward trends. Temporal variability of eastern China was briefly associated with El Niño...
The quality controlled (RAW) and homogenized (ADJ) radiosonde temperatures within 850–30 hPa collected at 118 stations in China are compared, on a monthly mean basis, with the extracted from 8 reanalysis datasets (REA) including NCEP-1, NCEP-2, ERA-40 (ECMWF 45-yr Reanalysis), ERA-Interim, JRA-55 (Japanese 55-yr 20CR (20th Century MERRA (Modern Era Retrospective-Analysis), CFSR (Climate Forecast System Reanalysis). Average differences, correlations, standard deviations, linear trends among...
Abstract Soil moisture (SM) is a critical element of the hydrological cycle, land surface processes, and energy balance. However, low spatial resolution commonly used SM products limits application in agriculture eco‐hydrology cold arid regions. In this study, normalized difference soil index (NDSI) bare (BSI) were added to traditional downscaling factors including temperature, vegetation index, digital elevation mode, apparent thermal inertia, Albedo, temperature dryness as they are more...
Abstract Trends and uncertainty in radiosonde temperature records for six sample stations eastern China are assessed. Results from a complex approach using metadata two‐phase regression (M‐TPR) to capture known unknown events respectively compared with an ensemble of possible solutions generated by the Met Office automated homogenization system (QUARC). Independent satellite Microwave Sounding Unit (MSU) record used validate breakpoints over era. Differences treatment strictness statistical...
Abstract Currently, the satellite Microwave Sounding Unit (MSU/AMSU) datasets developed from three organizations—Remote Sensing Systems (RSS), University of Alabama at Huntsville (UAH), and NOAA Center for Satellite Applications Research (STAR)—are often used to monitor global long-term trends temperatures in lower troposphere (TLT), midtroposphere (TMT), total (TTT), stratosphere (TTS), (TLS). However, trend these over China has not been quantitatively assessed. In this study, decadal...

We built a large (approximately 4,000 m**2) water Cherenkov- type muon detector array under the existing Tibet air shower at 4,300 m above sea level, to observe 10-1000 TeV gamma rays from cosmic-ray accelerators in our Galaxy with wide field of view very low background level. A gamma-ray induced has significantly less muons compared one. Therefore, we can effectively discriminate between primary and events by means counting number an event array. make status report on experiment.
